Description: PR summary When outputting files using the "core 14 fonts" (e.g., rcParams['pdf.use14corefonts'] = True), text will be measured using our internal AFM files instead of any external files. While we don't have a full API decided for how to pass full Text objects through backends, add in a small internal helper to allow the PS/PDF backends to override font height metrics with the AFM files. Note, because there is still some small difference in how we calculated line spacing, there is some small difference in the result from before. But it no longer changes results depending on whether Helvetica is installed globally.
